Aqueous solutions of surfactants exhibit remarkable differences in their adsorption properties on metal surfaces. This study evaluates the adsorption of surfactant mixtures on zinc metal surfaces. The adsorption of single surfactants cocamidopropyl betaine (CAPB) and sodium dodecyl benzenesulfonate (SDBS) and their mixtures from aqueous solution at mole fractions of 0.00, 0.25, 0.50, 0.75 and 1.00 on zinc powder at 25 °C was studied. The surface tension of the single and CAPB/SDBS surfactant mixtures was measured in the presence and absence of 2 % zinc powder to determine the adsorption isotherms. The depletion method was employed to carry out the adsorption investigation. The amount of the surfactant adsorbed was also calculated from the shaded area between the surface tension versus concentration curves of these surfactants in the presence and absence of 2 % zinc powder. The highest adsorbed amounts were found to increase with the SDBS content. Furthermore, scanning electron microscope (SEM) images of zinc sheets in solutions containing single or mixed CAPB/SDBS surfactants were taken in the presence and absence of 0.05 M HCl. The micrographs indicated that the CAPB-SDBS surfactant layers formed by precipitation can protect zinc metal from acid corrosion.

The aim of the present study was to evaluate the potential applications of micellar extracts derived from Bistortae rhizoma, Fraxinus excelsior, and Romex crispus as components of hair shampoos and to examine the impact of these micellar extracts on the specific properties of the formulated cosmetics. The antioxidant activity, polyphenol content, and vitamin C content of the plant materials selected for the study were assessed. In addition, particle size analysis was performed for the obtained micellar extracts. The shampoos prepared on the basis of original formulations were evaluated for irritation potential, viscosity, foam stability index, and color. The plants evaluated in the study exhibited a high level of antioxidant activity, and the derived extracts were found to contain micellar aggregates. The application of the extracts was shown to reduce the skin irritation potential of the shampoos and reduce their viscosity. In addition, the formulated shampoos were characterized by a high foam stability index. Substantial variations in the color of the cosmetics were observed upon the introduction of the micellar extracts into the formulations.

Ellagic acid (EA) is a natural antioxidant found in many fruits and vegetables. However, its solubility in water is poor, which limits its application. To overcome this limitation, the surfactants Span 20 and Tween 60 are used to increase its solubility in water. FTIR, TEM and laser particle size and zeta potential analysis were used to characterize the morphology and structure of ellagic acid emulsions. The antioxidant activity of surfactant-compatible ellagic acid was determined using various antioxidant evaluation methods such as DPPH and ABTS radical scavenging, reducing power and total antioxidant activity. The results indicate that the solubility of ellagic acid in water was improved by the addition of Span 20 and Tween 60, and ellagic acid formed complex particles in combination with Span 20 and Tween 60. Compared to pure ellagic acid, the antioxidant activity of ellagic acid lotion was significantly enhanced.

The laundry process is energy-intensive and an important target for reducing residential environmental impacts. Category life-cycle analysis (LCA) studies show the primary environmental impact is due to the energy consumed during the use phase, mainly for heating water. However, doing the laundry is a complex socio-technical system, where addressing sustainability requires not only technical levers but also an understanding of users’ habits, practices, and belief systems. This study investigates if and how consumers change their laundry habits and product satisfaction when using a technically lower-performing eco-brand detergent compared to a heavy duty high-performance detergent. These represent two distinct sustainable innovation strategies within the detergent industry, i) high-performance detergents formulated to provide excellent cleaning performance at lower wash temperatures and ii) eco-brand detergents optimized for a lower ingredient footprint but reducing cleaning performance. It is hypothesized that consumers may compensate in ways detrimental to the overall sustainability of the laundry lifecycle. The results showed significantly lower consumer satisfaction with the eco-brand performance which led to compensatory behavior including increased detergent dosing and higher wash temperatures. This study confirms the importance of detergent cleaning performance for sustainable consumer habit changes regarding lower wash temperatures.

Foam has been widely used in drilling, well washing, and oil driving during the development of oil and gas fields. Although air foams have been successfully employed as an enhanced oil medium, the oxygen they contain can seriously corrode piping systems, which can have a negative influence on output. This work used a combination of sodium dodecyl sulfate (SDS), dodecyl aminopropyl betaine (LAB), sodium dodecylbenzene sulfonate (SDBS), and cosurfactants to solve the problem above. The corrosion inhibitor hydrazine hydrate (N₂H₄·H₂O) was added as corrosion inhibitor. The foaming (air)-corrosion inhibitor all-in-one (SLN) was obtained with the formulation of SDS: LAB: N₂H₄·H₂O = 8:2:4. The foam volume of 0.7 % SLN was measured to be 515 mL at room temperature with a half-life of 4.1 min using the stirring method. The initial foam height of this all-in-one agent was measured to be 15.6 cm at 30 °C using the Roche foaming method. The foam height was still maintained at 15.5 cm after 20 min with a foam height retention of 99.2 %. The foam height retention rate was 50.0 % at 70 °C. Moreover, the formulation had good salt resistance to common inorganic salts in oilfield water. It should be emphasized that the SLN all-in-one agent has strong corrosion inhibition performance, and the corrosion inhibition rate can reach up to 96.9 %. The surface tension of this SLN all-in-one agent was reduced to 27.8 mN m−1 at a concentration of 0.1 %. It indicated that the all-in-one agent might increase the stability of the foam by decreasing the surface tension, thus improving the persistence of the foam and the effect of the repelling oil.

Household detergents are a source of water pollu-tants that adversely affect crops. These pollutants not only reduce plant growth, but also have a negative impact on the environment. To investigate the effect of handwashing liquid on the germination characteristics of wheat, mung bean, and chickpea, a study was conducted using a completely randomized design with three replications. Water contaminated with different concentrations of handwashing liquid ((0, 0.01, 0.1, 1, 10) % of handwashing liquid) was used as treatment. The results showed that with increasing concentration of the contaminant, germination characteristics such as seed germination percentage, caulicle length, radicle length, and seed vigor decreased. Wheat was the most sensitive to detergent concentration compared to the other two plants, with the lowest detergent concentration causing a severe reduction in its germination traits. Therefore, farmers using water contaminated with household detergents need to be aware of its concentration to ensure healthy plant growth.

To improve the insufficient performance of anion on cationic surfactants and to further study the influence of anion on the surface properties, a cationic surfactant (cetyltrimethylammonium p-toluenesulfonate, CTATS) was prepared, and the relevant surface properties, including surface tension, critical micelle concentration, foaming ability and stability, corrosion inhibition and oil displacement efficiency were studied. Compared to cetyltrimethylammonium chloride (CTAC), CTATS exhibited higher surface activity, lower foaming volume, higher foam stability, higher corrosion inhibition performance and oil displacement efficiency. The results indicate that the CTATS has better performances as a surfactant type in oil and gas fields.

Foamers with high resistance to condensate, salinity and high temperature play a crucial role in gas well deliquification. In this study, we developed an efficient foaming mixture containing a Gemini surfactant (CAGB), a betaine surfactant (CAPB) and sodium lauroyl glutamate (SLG), which exhibited excellent foaming performance (at a molar ratio of 3:3:4 and a dosage of 20 mmol L−1) with a foam volume of 440 mL and a half-life of 11 min. The optimized CAGB/CAPB/SLG mixture showed exceptional liquid unloading and foaming ability under high methanol (up to 40 vol.%) and condensate (up to 50 vol.%) content conditions. Trisodium aminotriacetate (NTA) facilitated the liquid unloading performance at a salinity of 90 g L−1. With 10 vol.% methanol, the liquid unloading rate of CAGB/CAPB/SLG foam at 90 °C could be increased to 90 %. Furthermore, surface tension and morphology analysis confirmed the presence of synergy within the CAGB/CAPB/SLG mixture in foaming, foam stabilizing and liquid unloading ability.

Analysing the possibilities of obtaining biosurfactants and using waste materials as substrates for their production allows us to emphasize that biosurfactants are in line with the ideas of sustainable development and the protection of non-renewable resources. These ideas also apply to the engineering and technology of cosmetic products. For this reason, and because of the multi-functionality of biosurfactants, their role and widespread use in cosmetic formulations is likely to increase. Biosurfactants tend to have good surface properties. Their structural diversity results in differences in biological, antioxidant or biocidal activity. The paper presents the potential of biosurfactants that could be used in the composition of products dedicated to the fight against the problems of ageing skin. Particularly important in the skin ageing process is the fight against radicals and the prevention of collagen loss in the skin. The overall appearance of the skin also depends on the level of hydration and roughness. Biosurfactants also have an effect on the melanogenesis process, controlling hyperpigmentation. A relatively new approach to the fight against skin ageing emphasizes the role of the microbiome, and available research also points to the correlation of biosurfactants with maintaining the correct structure of the microbiome.

The objective of the research was to investigate the influence of kerosene and oleic acid on emulsion formation. The two solutions were combined to form an emulsion by dispersing the kerosene solution into small droplets within the aqueous phase with the assistance of oleic acid. The surfactant reduced the interfacial tension between the two solutions, facilitating the emulsification process and stabilizing the droplets formed. A comprehensive understanding of the variables that control to the formation and stability of emulsions is essential for their effective development. For this purpose, the stability of oil-in-water emulsions was evaluated by measuring droplet size, turbidity, zeta potential, surface tension, and conductivity. Improved emulsion stability was correlated with smaller droplet size, increased turbidity, and reduced surface tension. The results of this research have significant potential for a variety of industrial applications.
